Biography
Aygul Zagidullina studied Applied Mathematics, focusing on applications in Economics and Finance. She obtained her Ph.D. in Quantitative Methods, specializing in the Estimation of High-dimensional Covariance Matrices through the use of Regularization techniques and Factor Models.
Her academic background at the intersection of Statistics, Computer Science, and Data-driven Inference enabled her to succeed in industry as a Quantitative Modeler and Data Scientist.
She continued her education in Computer Science with specialization in Machine Intelligence at ETH Zürich, obtaining broad expertise in AI & ML domain. Her interest centers around the convergence of Data-driven solutions and its potential for societal benefit.
Aygul has many years of teaching experience at various levels: Bachelor, Master and Ph.D.
She has written the university level textbook on High-Dimensional Covariance Matrix Estimation with Springer Nature (Switzerland), that came out in 2021.
Aygul Zagidullina is also the co-organizer of the Women in Data Science conference in Zürich, WiDS Zürich and a member of Women in AI initiative.
